¿para que se utilizan los métodos de fraccionamiento de fases?

What are phase fractionation methods used for? well They apply to the prefractionation of the sample to obtain less complex protein mixtures for an easier analysis; they are also used as a means to evidence specific proteins or protein classes otherwise impossible to detect.

Explanation: in spanish /

Se aplican al prefraccionamiento de la muestra para obtener mezclas de proteínas menos complejas para un análisis más fácil; también se utilizan como un medio para evidenciar proteínas específicas o clases de proteínas que de otro modo serían imposibles de detectar.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
